Tarkov Armor Pen Calculator

🛠️ What Is the Tarkov Armor Pen Calculator?

The Tarkov Armor Penetration Calculator is an online tool that calculates the chance of your ammo penetrating enemy armor based on three key factors:

  1. Armor Class (1-6)
  2. Current Durability (%) of the armor
  3. Penetration Value of the ammo you’re using

This calculator uses an approximation of the same formula popular within the Tarkov community to give you a quick, realistic idea of whether your shot will penetrate.

⚙️ How Does It Work?

The tool calculates the penetration chance using this simplified formula:

PenChance = PenValue - (ArmorClass × 15) + 15 + ((Durability / 100) × 5)

Then:

  • If the calculated chance is above 95%, it’s capped at 95%.
  • If it’s below 0%, it’s set to 0%.
  • The result is rounded down to the nearest whole number.

This formula balances complexity and realism, helping players strategize more effectively during firefights.

🧭 How to Use the Tarkov Armor Pen Calculator

Using the tool is incredibly simple. Here’s a step-by-step guide:

  1. Select Armor Class
    Choose from Class 1 to Class 6 based on the armor your enemy is likely wearing.
  2. Enter Armor Durability (%)
    Input the remaining durability of the armor. You can estimate this during a raid or when inspecting found armor.
  3. Enter Ammo Pen Value
    Type in the penetration value of your ammunition. This can usually be found in ammo charts or in-game descriptions.
  4. Click “Calculate”
    Instantly receive the penetration chance and a descriptive effect that tells you what to expect from your shot.
  5. Reset Easily
    Use the reset button to quickly clear your inputs and start a new calculation.

📊 Example Use Case

Let’s say you’re using 7.62x39mm BP ammo with a pen value of 47, and your enemy is wearing a Class 4 armor with 70% durability.

Plug in the values:

  • Armor Class: 4
  • Durability: 70
  • Pen Value: 47

Calculation:

PenChance = 47 - (4 × 15) + 15 + ((70 / 100) × 5)
           = 47 - 60 + 15 + 3.5
           = 5.5 → Rounded down to 5%

Result:

  • Penetration Chance: 5%
  • Effect: Very low chance. Penetration is almost impossible.

Now you know it’s better to aim for an unarmored spot—or switch to better ammo.

🎯 Why Use This Calculator?

  • Quick and Accurate: No need to memorize ammo charts or do the math.
  • Mobile-Friendly: Optimized for mobile, so you can use it mid-raid.
  • Descriptive Feedback: More than just a percentage—get context.
  • Clean UI: No ads, clutter, or unnecessary distractions.

🧠 Frequently Asked Questions (FAQs)

1. What is a good penetration chance in Tarkov?

Anything above 70% is generally considered reliable. Below 40% means penetration is unlikely.

2. Does this tool consider blunt damage?

No, this calculator focuses purely on penetration chance, not blunt trauma damage.

3. What’s the max penetration value in Tarkov?

Pen values vary by caliber, but the highest commonly seen is around 60-70.

4. What’s the highest armor class in Tarkov?

Class 6 is the highest, often used in top-tier armored rigs and helmets.

5. Where can I find ammo penetration values?

You can find them on community ammo charts, EFT wiki pages, or in-game tooltips.

6. Is armor durability that important?

Yes! Armor with lower durability becomes less effective at stopping rounds.

7. Does this tool update with new patches?

As long as the formula remains valid, the tool works. We’ll update it as needed for new game versions.

8. Can I use this during a raid?

Absolutely. It’s mobile-optimized for quick access between matches.

9. What if my ammo isn’t listed?

Just enter the known penetration value. If you don’t know it, check an EFT ammo chart.

10. Is penetration always better than damage?

Not always. High damage rounds are great against unarmored targets. But pen matters more against geared players.

11. Do helmets have the same calculation?

Yes, the formula is the same, though helmets usually have different durability values.

12. Is the result 100% accurate?

It’s based on an approximation formula used by the community, and is very close to in-game behavior.

13. Will this tool be updated with patch changes?

Yes, we monitor patch notes and update accordingly.

14. Does armor class multiply damage reduction?

No, it simply represents the strength of the armor. Higher class = stronger protection.

15. Can I embed this on my website?

Contact us for integration options.

16. Is there a way to add ammo presets?

Currently, no. But that feature is planned for future updates.

17. Why is the max pen chance capped at 95%?

To reflect in-game mechanics, where absolute certainty is rare due to RNG.

18. Why do some shots fail even with 90% chance?

There’s always a chance for failure due to randomness and angles.

19. Does this tool account for ricochets?

No, ricochets depend on angles and are outside this calculator’s scope.

20. Is this tool free to use?

Yes! 100% free with no login required.
